Specification of Letters Patent.

Patented Oct. 29, 1907.

Appuomon nessuna 24.1907. sesam. 380.576.

declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to whichl itappertains to make and use the same.

My invention rela'tes to invisible hinges for cabinets, pianos, or otherarticles of furniture, and wherever a particularly neat appearance isdesired.

The object of my invention is to produce a hinge oi this character whichshall be at all times entirely concealed from view, and which shallpermit the parts to which it is attached to open so wide that they maylie flat along side each other.

To these ends my'invention consists in providing two main sections of ahinge 'which are readily separable from each other, and which are at alltimes concealed by a cover.

My invention also consists in the novel combination of parts hereinafterdescribed and particularly pointed out in the claims.

Referring to the accompanying drawingsforming a part` of thisspecification-Figure 1 represents my hinge with the parts to which it isapplied opened out to about 90 andshowing only the cover of the hingeexposed. Fig. 2 is a sectional view taken through the top of the hingecasing, showing the various hinge members including the floating frame,in place. Fig. 3 is a sectional view, taken on the line 3-3 of Fig. 2,but also showing the parts to which the hinge is applied. Fig. 4 v

' on the line .5-5 of Fig. 2, and showing the hingecasings foldedbackparallel to each other. Fig. 6 -is a sectional view taken on the line'6-6 of Fig. 2, and showing the lhinge"casings closed as they are in Fig.2. Fig. 7 is a perspectivel view showing one of the hinge casings, thehinge plate that goes therewith, and the floating frame. Figs. 8 and( 9are perspective views of the bolts that vslidingly secure the partstogether.

Like numbers designate like parts in all the views.

I The hinge consists of-two main sections, each section composed of 'ahinge casing .4, and a plate 11, pivoted thereto. It also consists of acover 3, a floating frame 22, and two bolts 17.

Each casing 4 is provided with the guide horns 5, the guide platesShaving theguide pins 7, and thecut away lower edges 8, and the hingeeyes 9. These hinge eyes 9 on one casing 4, are longitudinally displacedon the casing with respect to the corresponding hinge eyes on the othercasing 4, so that the two sets of hinge eyes on the two casings 4 maycome together and register in the same straight line, see- Fig. 2.Corresponding to the hinge eyes 9 on each casing 4, are another set ofhinge eyes 10 on hinge plates 11, one hinge plate for each casing 4, anda plurality of short pins 20 pass through the hinge eyes 9 and 10 ofeach main hinge section, and of course lie in the same straight linewhen the parts are in the position shown in Figs. 2, 3 and 6. vTheseplates 11 are provided with housings 12 having solid parts 13 cut awayon their under sides at 14,and curved guides 15. Holes 16 are madethrough the solid parts 13 to accommodate the bolts 17, and cut awayplaces 19 are provided next to the solid parts 13 to accommodate thecurved guides l5 on opposite housings when the hinge is operated, aswill appear more fully hereinbelow. Each of the plates 11 are likewiseprovided with cut away places 20 and 21, each to accommodate two guideplates-6 and 27, as will appear below.

The loatinglrame 22 is provided with the side strips 24, the end pieces25, and the bottom strips 26. Each of these bottom strips are providedwith two guide plates 27, one on each. side, as shown, and each plate 27is provided with curved guide surfaces having the upp'er notches 28, theapex 29, and the lower notches 30. The notches 28 in one pair of platesare located opposite the notches 30 in another pair of plates, as shown.-The bottom strips 26 are also provided with the holes 18, as shown, andthe cutaway places 31.

In assembling the parts, the two plates 11 are first hinged to the twocasings 4by matching the hinge eyes 9 and 10 and by inserting aplurality of short pins 20 throughl said eyes. The two main sections ofthe hinge thus formed, are next brought together with their hinged sidesparallel as shown in Fig. 5, and the hinge plates turned to an angle ofabout 90 with the said sides, in which position the guide plates 6 ofthe casings 4, are about one-half within and one-half without thehousings 12. One of the strips24 of the oating `frame is next removed,and the bottom strips carrying the guides 27 are thrust underneath eachplate 11 and between the same and the hinge edge of each casing 4, beingcareful to see that the said guides 27 enter the housings 12 on theplates 11, and that the pins 7 on the guide plates 6 contact with theguide surfaces 28, 29, 30 of said plates 11, as shown. In this positionof the hinge, the bolts 17 may be thrust through the holes 18 from theoutside, and the strips 24 that had been removed fromthe floating frame22, may be now secured in place by solder or otherwise.

Upon opening and shutting the hinge after assembling the parts, asdescribed, it will be found that the short pins 20 all aline, when thecasings 4, are in the same straight line, as shown in Fig. 2, and thatthey separate, as shown in Fig. 5, when the said casings are broughtparallel to each other while the floating frame seems to remainstationary and the solid portions of the hinge plates slide on the'bolts17. The guide horns 5,. enter between the strips 24 and the housings 12,as shown, and .force the latter inward as the casings are carriedfrom-the position shown in Fig. 5 to that shownf in Fig. 4, and finallyto that shown in Fig.` 3. In opening out the casings from the positionshown in Fig. 3 to that shown in'Eigs. 4 and 5, the guide horns 5,merely slide out from between the strips 24 and the housings 12, whilethe plates 6 on the casings 4, force the said housings to slide'outward, or apart on the'rods 17.v The casings 4 are fastened in theparts to' be'hnged, as shown, and holes 33 are provided in the plates11, for accommodating a screw driver, when the said plates are at rightangles to the hinge bottom of said casing and the screws shown in Fig. 3are to be inserted.

It will be seen that4 the floating frame 22 remains practicallylstationary with respect to any swinging movement of the housings '12,or in other words, this frame and these housings turn on a shiftingpivot passing through the two sets of short pins 20. It results fromthis that the cover 3, will likewise .partake of the same motions, andalways `occupy the space uncovered between the hinged parts l and 2, asshown in Figs. 4 and 5. The 'parts of the hinge are therefore alwaysconcealed and a neat appearance secured.

Inpractice, I prefer to make my hinge of brass, al# though any desiredmaterial may be employed, and to cast the casings 4 with the horns 5,the plates 6 and the hinge eyes 9 integral therewith. The plates 11 maybe either stamped, or casa-and the floating frame with one side removedmay be cast inione piece, and the said side in a separate piece, andthen secured to said frame in any `suitable manner..
